CRUSHING BREAKING Krause said. ���We���re inefficient for two reasons. One is the concept that more water is more efficient. Then, it���s a lack of understanding that there is new technology ��� for example, dewatering screens, different pumps, different additives such as flocculants, that can greatly reduce the cost of the washing operation.��� To Krause, high water use in washing creates two types of costs. ���Whatever water you put in, you���ve got to take out and treat,��� he said. ���Secondly, we see a lot of waste because water tends to carry particles with it and parti��� cles that you wish to retain ��� your sand ��� are now going somewhere you don���t want them to go. There���s a cost to going in there and reclaiming that. If that sits in the bot��� tom of the pond, at some point, you���ve got to clean out your pond.��� There���s a cost to going in there and reclaiming that. www.rockproducts.com ROCKproducts ��� MARCH 2013 39
